A series of n B, construcled so enoirefre the equipped withperipheral bros er said segments and teeth beingsevess tschshle to anddetachable from o est and so end from file rim, will he presohtly eslsioed.

of undercut or dove-tallform which is adapted to be removebly fitted loa correspondmg recess ill) or she periphery of :21 seg ment. Eachsegment 15 provlded as his respective lateral edges with a series ofthese races es, those on one side preferably alternating with those onthe other, as indicated most clearly in Fig. 4c, whereby two rows ofteeth, in staggered relation to each other, may be employed, as bestillustrated in Fig. 3. The base 'or root of each tooln com pletely fillsthe recess to which it is applied and lies flush with the outer edge ofthe segment, so that when the respective segments thus equipped will thetwo rows ofle'eth are assembled side by side the contiguous edges of thesuccessive segments effectually lock 0 the teeth in place and obviateany liability of their displacement. (See Fig, 2.)

res

-- seen that in the event of a tooth or teeth the roller, which connecrecessed to' interlock'with such readily mserted in t taile'annecti'ons; the

ments and therein s pletely suiddcd with teeth throughout itscircumference; and that the entire series of toothed segments canthen'be quickly and reliably clamped in place by applying the groovedrings D to" the respective ends of the roller and segments. It will alsobe upon the roller being broken while in service, the segment orsegments containing the particular defective tooth or teeth can bereadily detached from the roller; such tooth teeth can. be removed; anew tooth or teeth can be substituted therefor, and the segment orsegments can. then-be replaced and locked on the roller.

In Fig, 5, I have shown a s ight modification of "my invention whereintwo rows 0 segments are indicated as arranged in endwise alinement witheach other, theinner or abutting ends of the segments of the.re-=spective rows being oppositely recemed to provide a dove-tailgroove forthe regeption of a circumferential dove-tail tongue 11 on tion thusserves, in conjunction with the outer end clamp rings to lock thesegments securely, though detachably, to the roller; v

In Figs. 6, 7'and 8 Ihave illustrated another modification of thepluralrow form just described. In this construction the clamp-rings D areomitted; the outer end walls of the circumferential rooves of the rollerare undercut to provide inclined or dove-tail tongues, as at 12, and theouter ends of the segments are correspondingly tongues and thus securethe segments "against radial and e'ndwise displacement .on the roller.

In order to permit the ready application of the se ments to theroller,'the outer end walls of t e c rcumferential grooves are each cutout at a suitable point on the end of the roller. The studded segmentsof each row' are individually applied to. the roller by Way of theopening til the latter is fully This block in the form 12 thus provided,and such segments are successively moved around the circumference of theroller and into/engagement at their respJective ends with [the annulardove-tail m'em ers of the roller, un-

encircled by the 'segments. Thereupon a filler block,'as D", is appliedto theopening l2 and secured to the roller by means of a screw, as 7, soas to retain the circular series of segments in in-' terlockingengagement with the roller.

illustrated is pro\ portion "8' whilr vided with a shouldered & flangedrim of the enters a recess 13 in'the roller, and also with lateraltongues 14 which fit-correspondin grooves in the walls of the opening,thus e ectually relieving the screw-7 from radial thrust during'theoperation of the roller.

In'Figs. 9 l0 and 11 I have shown still anqther modification wherein thetoothbearing sections or members comprise a series of rings B assembledside bv side on the circumference of the roller, the cutemost rings '6,to receive the correspondin beveled wallsof the clamp rings D whicdetachablyloek .the entire series of rings in place. 'lo-prcvent theserings from turning relativcly to the body of the roller, they areprovided on their inner. faces with transverse key-ways 15 which-arearranged in aline-' ment. with and receive a key or leather 16'suitably-dis osed on said body. The peripheral rings are provided attheifilat eral edges with the dove-tail recesses 10 for the receptionand retention of the basal ends of the teeth 0, the latter, as in thepreviously described constructions, being positively held in place bythe opposing edges of the -respective rings.

1t is to be understood that my invention is not limited to the specificdetails of construction herein shown and described, as the structure maybe modified in various particulars without departure from myjnvention;for exam 1e, 1110116 aspect of my invention, the brea 'er teeth may bepermanently secured to or be integral with the detachable segmental-orring members.
